So my 7 day park Hopper plus ticket that I bought via Viator is only valued at $642.23 according to the cast member I just spoke to about upgrading to the Sorcerer's Pass.

The ticket is $729 on Disney's website...I paid $620 with the 15% off Viator code. So if what the first cast member says is true (and the purchase doesn't track on RMN) then it isn't a good idea to buy tickets via Viator to then upgrade.
Learn from my mistake! (and also don't tell my husband my math was wrong...I did some serious Disney math to make It seem like I needed an annual pass instead of the $99/day 4 park ticket

). Off to book more vacations so I can justify this purchase!
